Turn your M-LOK® forend into a fast, competition-ready platform with the MDT Sporting Goods 8.60" M-LOK ARCA Rail (103570-BLK). Engineered to the ARCA-Swiss standard used by precision shooters and photographers alike, this lightweight, hard-anodized rail lets you slide, position, and lock bipods, clamps, and tripods anywhere along its length—no more fixed studs or clumsy adapters. Whether you’re building a field-tough hunting rifle or a PRS barricade crusher, this 8.60" section gives you the stability and tool-free positional freedom modern shooting demands.

Why Shooters Choose This MDT ARCA Rail

• True ARCA-Swiss Interface: Works with common ARCA clamps, leveling bases, and tripod heads so you can transition from barricade to tripod in seconds.

• Direct M-LOK® Mounting: Bolts straight to most M-LOK forends and chassis—no drilling, no special bottom metal, just a clean, secure install.

• Optimized 8.60" Length: Long enough for wide bipod stance and micro-adjustment on bags and barricades while staying compact for field carry.

• Hard-Anodized Black Finish: Durable, low-glare coating that resists scuffs, corrosion, and harsh weather.

• Precision Machined Aluminum: Stiff, lightweight section maintains a solid interface under load for consistent point of aim.

• Flush, Low-Snag Profile: Chamfered edges and countersunk fasteners help the rifle glide on bags and clear obstacles.

Real-World Benefits

• Rock-Solid Stability: Broad ARCA interface spreads load over a larger surface area for less flex and better tracking.

• Travel & Field Friendly: Keep weight down and ditch multiple adapters by standardizing on ARCA.

Ideal Use Cases

• PRS/NRL Competition: Smooth transitions between props; fine-tune fore-aft balance under time pressure.

• Hunting & Field Shooting: Tripod-ready stability for glassing and longer shots with minimal setup.

• Rimfire & Trainer Builds: Mirror your match rifle controls and workflow on a practice rig.

• General Precision Work: A stable, repeatable interface for chronograph sessions, load development, and zeroing.

Installation Guide (Quick)

1. Verify Fit: Confirm your forend/chassis has compatible M-LOK slots where you want the rail.

2. Align & Seat: Place the 8.60" ARCA rail along the centerline; insert M-LOK T-nuts through the slots.

3. Torque: Tighten per M-LOK spec (typically ~35 in-lb on screws; follow manufacturer guidance).

4. Function Check: Clamp your ARCA bipod/tripod and verify smooth travel and positive lockup.

5. Re-Check: After your first range session, confirm screw torque.

Compatibility Notes

• Forends & Chassis: Fits most M-LOK handguards and MDT/other precision chassis systems with standard slot spacing.

• ARCA Gear: Accepts ARCA-Swiss standard clamps; some heads may vary—check clamp width and jaw adjustment.

• Gas System/Barrel: Ensure clearance for gas blocks and barrels on semi-autos; keep rail centered for best balance.

Care & Maintenance

• Wipe rail surfaces after dusty or wet use to protect the anodized finish.

• Keep clamp faces free of grit for maximum holding power.

Frequently Asked Questions

Q: Will this rail fit my non-M-LOK handguard?
A: This model mounts via M-LOK only. If your forend uses KeyMod or proprietary slots, use an adapter or a rail designed for that system.

Q: Does it include mounting hardware?
A: MDT rails are typically supplied with M-LOK screws and T-nuts. Verify contents on receipt and follow M-LOK torque specs.

Q: Can I run a tripod directly off the rail?
A: Yes—any ARCA-Swiss clamp or head that accepts standard ARCA dovetails can secure directly to the rail.

Q: Is 8.60" long enough for a wide bipod stance?
A: For most chassis/forends, 8.60" provides ample travel to optimize bipod placement and balance point without excessive weight or bulk.

Equip your rifle with the MDT Sporting Goods 8.60" M-LOK ARCA Rail (103570-BLK / 103570BLK, UPC 709951106471) and unlock smoother transitions, stronger stability, and true ARCA-Swiss versatility—on the clock or in the wild. Mount once, move fast, and shoot with confidence.
